--- Comment #4 from Ryan Schmidt <gcc at ryandesign dot com> ---
Thanks. If I remove the extern "C" then it fails with:
/opt/local/var/macports/build/_Users_rschmidt_macports_dports_lang_gcc5/libgcc-devel/work/gcc-5-20141109/gcc/graphite-optimize-isl.c:357:12:
error: use of undeclared identifier 'isl_band_member_is_zero_distance'
if (isl_band_member_is_zero_distance (Band, i))
^
The isl changelog, under the heading "Changes since isl-0.12", says "The
function isl_band_member_is_zero_distance has been removed. Essentially the
same functionality is available through isl_band_member_is_coincident, except
that is requires setting up coincidence constraints. The option
schedule_outer_zero_distance has accordingly been replaced by the option
schedule_outer_coincidence."
